Big Battery - 48V 2X KONG ELITE MAX 12K INVERTER KIT - LiFePO4 - 744Ah - 38kWh

The 48V Off-Grid Home Elite Max System is designed to power all electronic devices and heavy-duty home appliances in a 4-6 bedroom house. It can be used as a large-scale backup power system during emergencies or as a fully off-grid wind/solar power system for larger homes. This system is equipped with the latest inverter and battery technology at the best price in the USA.

The 48V/19kWh KONG Elite Max Battery, which is calibrated to the 12,000-Wh Growatt Inverter, comes with a built-in color LCD Smart Display and new LFP cells that are guaranteed to last for 10-15 years, depending on usage. All components and parts required for installation are included, and the system can be installed on your house within a day. The 48V Off-Grid Home MAX System is compatible with all AC, wind, solar, generator power, and/or any redundancy combination you may need.

The system connects to shore power, and the battery automatically charges when connected. The low-frequency inverter included in the kit eliminates power spikes in your home, extending the life of your electronics. This system features the safest LFP battery technology with Built-In Triple-Safety Redundancy features. It requires no maintenance and lasts 300% longer than lead-acid off-grid systems, and all battery packs come with a 10-year warranty.
